This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

Ccircus::circ_variable	Represents a variable in Circus serialization
Ccircus::utils::cxpr_stream< args >	Compile-time concatenation of multiple string_views into a single string_view
Ccircus::deserializer< IStreamT >	Parses structured circus-formatted input and exposes access to the parsed data
Ccircus::utils::enum_flag< T >	A utility class for strongly typed enum flags with bitwise operations
Ccircus::traits::exists< Ts, Us >	Checks if a type Ts exists among a variadic list of types Us
Ccircus::utils::detail::explode< rem, digits >	Compile-time recursion to split an unsigned integer into digits
Ccircus::utils::detail::explode< num >
Ccircus::utils::num_to_string< num >	Converts a compile-time unsigned integer to a string literal
Cstd::false_type
Ccircus::traits::is_vector< std::vector< T, A > >
Ccircus::traits::pair_inspect< T, std::void_t< decltype(std::declval< T >().first), decltype(std::declval< T >().second)> >
Ccircus::traits::is_vector< T >	Trait to determine if a type is a std::vector
Ccircus::traits::pair_inspect< T, typename >	Trait to determine if a type is a pair-like structure (has .first and .second)
Cfs...
Ccircus::internal::visitor< fs >	Helper struct to combine multiple callable objects into a single visitor
Ccircus::lexer__	Lexer for tokenizing input strings into Circus tokens
Ccircus::parser__	Parser for Circus token streams producing nested Circus variables
Ccircus::error::parser_reporter	Aggregates and manages parser error messages with support for logging and flushing

Cstd::runtime_error
Ccircus::error::parser_error	Exception class for parser errors, holding an error type flag and a message
Ccircus::serializer< OStreamT >	A flexible serializer for C++ objects, primitives, STL containers, and user-defined types

Ccircus::utils::detail::to_chars< digits... >
Ccircus::utils::detail::explode< 0, digits... >	Base case for explode recursion when remainder is zero. Inherits from to_chars to produce the final digit string
